Because vendors host applications in their own datacenters, companies don't have to concern themselves with hardware provisioning and software maintenance. By living in the Internet "cloud," these hosted applications simplify sharing and collaboration among employees. However, the experience of users living through the recent Google Apps outages could serve as a deterrent to some IT and business managers who might not be ready to ditch conventional software packages that are installed on their servers.

Accessibility of Web content to people with disabilities requires semantic information about widgets, structures, and behaviors, in order to allow Assistive Technologies to make appropriate transformations. This specification provides an ontology of roles, states, and properties that set out an abstract model for accessible interfaces and can be used to improve the accessibility and interoperability of Web Content and Applications. This information can be mapped to accessibility frameworks that use this information to provide alternative access solutions. Similarly, this information can be used to change the rendering of content dynamically using different style sheet properties. The result is an interoperable method for associating behaviors with document-level markup. This document is part of the WAI-ARIA suite described in the ARIA Overview.

OSCON 2008, Gonsalves made the announcement that, after several years of consideration, Google was releasing Google XML Pages (or GXP) under the Apache Open Source License.

At OSCON 2008, Gonsalves made the announcement that, after several years of consideration, Google was releasing Google XML Pages (or GXP) under the Apache Open Source License.

Originally developed as a Python interpreter that produced Java source code, gxp was rewritten in 2006-7 to be a completely Java based application. The idea behind gxp is fairly simple (and is one that is used, in slightly different fashion, for Microsoft's XAML and Silverlight) - a web designer can declare a number of XML namespaces that define specific libraries on an XHTML or GXP container element, intermixing GXP and XHTML code in order to perform conditional logic, invoke server components, define state variables or create template modules. This GXP code is then parsed and used to generate the relevant Java code, which in turn is compiled into a server module invoked from within a Java servlet engine such as Tomcat or Jetty and cached on the server.

The need for openness led major players in the virtualization market to jointly create a proposed standard, the Open Virtual Machine Format (OVF). Members of the team were XenSource, which is owned by Citrix, VMware, Microsoft, HP, IBM and Dell. The OVF was submitted to the Distributed Management Task Force (DMTF), which develops management standards and promotes interoperability for enterprise and Internet environments. The DMTF accepted the proposed standard in September. The OVF will package all VMs with an XML wrapper that will let them run on any virtualization platform. It will also incorporate a security check to ensure that the VM has not been tampered with; metadata about what hardware or hypervisor the VM can run on; and a license check. The DMTF said the OVF will be rolled out this year.

Canonical, Ubuntu's parent company, is finally taking serious action on its long-announced plans to become a serious enterprise Linux player. The Isle of Man-based Linux distributor isn't just targeting data center servers, although that's on its list.

The plan is for VARs (value added resellers) and system integrators to brand the complete package under their own names.

Cloud computing is a paradigm shift in how we architect and deliver scalable applications. In the past, successful companies spent precious time and resources building an infrastructure that in turn provided them a competitive advantage. It was frequently a case of "You build it first and they will come." In most cases, this approach: Left large tracts of unused computing capacity that took up space in big data centers. Required someone to babysit the servers. Had associated energy costs. The unused computing power wasted away, with no way to push it out to other companies or users who might be willing to pay for additional compute cycles. With cloud computing, excess computing capacity can be put to use and be profitably sold to consumers. This transformation of computing and IT infrastructure into a utility, which is available to all, somewhat levels the playing field.

According to Amazon’s estimates, businesses spend about 70 percent of their time on building and maintaining their infrastructures while using only 30 percent of their precious time actually working on the ideas that power their businesses.

"The Industry Standard reports that Dell is trying to trademark the term cloud computing . The phrase entered the tech lexicon years ago, but Dell's application (serial number 77139082) was made in early 2007 to the US Patent and Trademark Office, apparently in connection with data center products and services that it was promoting around that time. A quick search of Google News indicates that Dell itself did not use the term in press releases or discussions with indexed English-language media sources from 1996 to 2006. Dell is not the first company to attempt to trademark this term: The Standard notes that NetCentric, a company that provided 'carrier-class Internet fax technology,' also gave it a shot in the late 1990s, but was rejected."

Xcerion has continued to work toward the general release of its XML-based "Cloud OS," a service based on Xcerion XML Internet Operating System/3 (XIOS/3). The announcement of an official name for the service brings the company a step close to that goal; it also certainly reassures investors like Lou Perazzoli, one of the core architects of Microsoft (NSDQ: MSFT) Windows NT, and Terry Drayton, founder of HomeGrocer.com, that Xcerion's technology is almost ready for prime time.

Icloud relies on an XML virtual machine for local (and offline) operation. It thus combines the advantages of remote computing -- a central point for software distribution, storage, and updates -- with the advantages of local computing -- execution speed and user control without a bandwidth bottleneck.

Icloud offers an intriguing technology that Xcerion is calling "gesture-based computing." Jonas Thornholm, CFO of Xcerion, believes it may be the service's "killer app." Gesture-based computing is essentially real-time content sharing. It allows users to drag and drop documents from their computer to a friend's computer in real time, as if they two machines were dual monitors powered by a single machine.

Meanwhile a Mountain View, Calif.-based startup called CherryPal just released a new mini-PC, known as the CherryPal, that is designed to operate solely via a Firefox browser. While the new machine, which will run on just 2 watts of power, has an embedded Linux-based OS, it's hidden from the user and is used mainly to boot up the browser to access common applications.

Several startups and open-source projects have built cloud-based operating systems, also known as WebTops, such as DesktopTwo, EyeOS, G.ho.st, and YouOS. To date these have mostly been of interest to the open-source development community, but the advent of browser-based "thin clients" like CherryPal and of projects like Midori indicates that fully cloud-based computing could make its way to the masses. Google is also said to be at work on a cloud OS, while a Swedish startup called Xcerion has gained attention for its hybrid, an XML-based system called iCloud.

Alfresco Software today announced the availability of Alfresco Labs (Beta) 3, the open source alternative to Microsoft® SharePoint®.  Alfresco Labs 3, formerly called Alfresco Community, offers Microsoft users greater choice by providing them with the first open source fully-compatible SharePoint repository.  With Alfresco Labs 3, companies can leverage existing investments in Linux and Java as well as Microsoft .NET connection software to significantly reduce their SharePoint total cost of ownership and maximize their hardware and software investments.  Alfresco Labs 3 will be available for download at http://wiki.alfresco.com/wiki/Alfresco_Labs_3

Sony Reader Opens to EPUB Format for Digital Books Adobe offers Digital Editions as display for portable documents William Pollard (will789)     Email Article  Print Article  Published 2008-07-28 16:36 (KST)    A new version of the Sony Reader for digital books will support the EPUB format and the Digital Editions software from Adobe.

A new version of the Sony Reader for digital books will support the EPUB format and the Digital Editions software from Adobe. The PRS-505 will be available with new software in the United States during August. Current owners can update through a download.

Version 1.74 is still regarded as experimental and there is still no easy way to create EPUB files from an Open Document in Open Office. Discussion on the DocBook Wiki suggests that not all DocBook features are currently supported and the installation for Open Office may not be easy enough for most people to follow.

"XML doesn't have the monopoly it used to have," Bray said. "It used to be that if you wanted to send messages back and forth across the wire, XML was the only game in town." "Clearly, there is going to more heterogeneity for wire formats, too," he added. "Increasingly, given that the future will have more than two programming languages, there will be a lot more messages being passed around."

Bray comes to the issue from a unique perspective. As a co-author of the original XML specifications, he helped create a language that at one point had been intended to become the lingua franca for all Web communications. He now admits that he wasn't entirely accurate in his original vision of where XML would end up.

"I was so completely wrong on everything," Bray admitted. "We thought we were going to replace HTML and that turned out to be a silly idea. It turned out be used for syndication feeds and purchase orders and a million other things, and that's fine. Things find their own level." However, in today's world of language proliferation, Bray has another favorite approach for exchanging information. "I am a strong partisan of the REST (define) approach, which provides a Web-based approach for integration of anything to anything," Bray said. "REST isn't tied to XML or JSON but it makes it easy to use either."

W3C today announced new standards that will make it easier for people to browse the Web on mobile devices. Mobile Web Best Practices 1.0, published as a W3C Recommendation, condenses the experience of many mobile Web stakeholders into practical advice on creating mobile-friendly content.

Until today, content developers faced an additional challenge: a variety of mobile markup languages to choose from. With the publication of the XHTML Basic 1.1 Recommendation today, the preferred format specification of the Best Practices, there is now a full convergence in mobile markup languages, including those developed by the Open Mobile Alliance (OMA). The W3C mobileOK checker (beta), when used with the familiar W3C validator, helps developers test mobile-friendly Web content.

W3C is also developing resources to help authors understand how to create content that is both mobile-friendly and accessible to people with disabilities. A draft of Relationship between Mobile Web Best Practices (MWBP) and Web Content Accessibility Guidelines (WCAG) is jointly published by the The Mobile Web Best Practices Working Group and WAI's Education & Outreach Working Group (EOWG).

Microsoft is incubating a componentized non-Windows operating system known as Midori, which is being architected from the ground up to tackle challenges that Redmond has determined cannot be met by simply evolving its existing technology.SD Times has viewed internal Microsoft documents that outline Midori’s proposed design, which is Internet-centric and predicated on the prevalence of connected systems.

The Midori documents foresee applications running across a multitude of topologies, ranging from client-server and multi-tier deployments to peer-to-peer at the edge, and in the cloud data center. Those topologies form a heterogeneous mesh where capabilities can exist at separate places.

The newly-renamed project is being expanded with workflow capabilities that Novell hopes will expand business usage. The Kablink project is Novell's effort to grow the market for open source collaboration solutions, and chip away at the hold that Microsoft's Sharepoint commands among small business users.

"We have a system inside of Kablink that allows developers to create business objects and these business objects model data," McConnell explained. "Then with the model of the data you can pass it views for forms and displaying the business model. So you can model a business object and then add collaboration items for that object." With the Kablink release, workflow capability is being added to the ICEcore collaboration features. A business user can now create a business workflow for a process -- be it approval, development or otherwise and attach that workflow to the business objects.

"We think our offering is unique; there are point solutions that have workflow embedded in them but the kind of social networking collaboration that we do, I don't know anyone that has a workflow component that can do the things that we can," McConnell claimed. "There are customers that have designed ISO 9000 processes with this, so it's a nifty thing to have, especially in an open source project."

According to Ts'o, the difference between organic and non-organic is related to how much influence a single corporation has in the development of an open source product. The broader the developer community around a project and the lower the barrier to contributing, the more organic it is. Citing Linux, Apache, Mozilla, and Eclipse among those in the organic open source camp, Ts'o singled out OpenSolaris as a prime example of non-organic open source. In fact, he objected to "Sun claiming that Solaris is just like Linux because it's open source"--a characterization that seemed to inspire his interest in asserting these definitions.

But it’s not all roses on the SharePoint front — especially when it comes to the growing trend by customers to use SharePoint not just as a set of loosely integrated applications, but as a development platform in its own right. A couple of new studies highlight the potential risks of which customers should be aware when betting big on SharePoint.

WSO2 is releasing on Monday WSO Mashup Server Version 1.5, an open-source product for deploying mashup services featuring Google Gadgets support and interfaces to relational databases and other data sources.

The mashup server uses JavaScript to describe logic for acquiring information, combining data, and exposing it to a user. Information can be acquired from sources such as Web services and scraped pages and published as a new Web service, feeds, Web pages, or notifications. Version 1.5 features stubs and templates for Google Gadgets, which can be hosted within Mashup Server or externally such as in an iGoogle page. A beta dashboard add-in is featured for hosting Google Gadgets within Mashup Server. Google Gadgets enable dynamic content to be placed on a Web page. Data services enhancements provide Web services interfaces to relational databases and other data sources such as Excel spreadsheets and comma-separated values.

A second survey showed that basic PC and network hardware, as well as professional services providers, would bear the largest proportion of spending cuts. It also showed that CIOs planned to emphasize economizing measures over investments in new technologies, with cloud computing emerging as the last item on their priority lists, despite the hype around it.

The CIOs indicated that server virtualization and server consolidation are their No. 1 and No. 2 priorities. Following these two are cost-cutting, application integration, and data center consolidation. At the bottom of the list of IT priorities are grid computing, open-source software, content management and cloud computing (called on-demand/utility computing in the survey) -- less than 2% of the respondents said cloud computing was a priority.

What sort of cloud computer(s) should we be building or expecting from vendors? Are there issues of lock-in that should concern customers of either SaaS clouds or PaaS clouds? I’ve been thinking about this problem as the CEO of a PaaS cloud computing company for some time. Clouds should be open. They shouldn’t be proprietary. More broadly, I believe no vendor currently does everything that’s required to serve customers well. What’s required for such a cloud? I think an ideal PaaS cloud would have the following nine features:

1. Virtualization Layer Network Stability

2. API for Creation, Deletion, Cloning of Instances
